What are Flexfields

Flexfields are a major part of Oracle Applications. Rather than knowing what a flexfield is, it is better to start with different types of flexfields and know what each type of flexfield mean.

There are 2 types of flex fields

Key Flexfield
Descriptive Flexfield

Key Flexfield:
A Key Flexfield looks like a normal text field on a form.


Descriptive Flexfield:
A descriptive flexfield appears on the form within 2 brackets [] with a character length 2.

When opened both types appear as a pop up window that contains sub fields.


So a flex field is a field made of sub fields(segments, values, valuesets).
Each segment has an unique name and a set of valid values and their descriptsion. A segment is represented as a single table column in a table.

'Linux-x86_64 Error: 28: No space left on device' While trying to start the database -- Error

SQL> startup mount pfile='/tmp/initdlfasp12.ora'
ORA-27102: out of memory
Linux-x86_64 Error: 28: No space left on device


This as you can see is on Linux x86 with 64 bit processor. We got this error after we changed SGA on 10gR2 database. So was sure that this is something to do with the OS.

Parameters to check for this are shmall.

shmall is the total amount of shared memory, in pages, that the system can use at one time.

$cat /proc/sys/kernel/shmmax
53687091200

$ getconf PAGE_SIZE
4096

As per Oracle SHMALL should be set to the total amount of physical RAM divided by page size.

Our system has 64GB memory, so change kernel.shmall = 1024 * 1024 * 1024 * 64 / 4096 = 16777216


Once this value is calculated you can modify Linux system configuration file directly.

$ su - root
vi /etc/sysctl.conf file:
kernel.shmall=16777216

and

# sysctl -p

Once this is done the database was started without any problem.
